Is it normal that one needs multiple runs in order to get down the number of fragmented files to 0?
When I run Defraggler the first time there were > 3.000 fragmented files on the hard disk. After the first run, about 350 files still were fragmented. The next run took it down to about 280 fragmented files. The next run to 180, and so on.
Shouldn't Defraggler bring it down to zero with only one run? Or is this technically not possible?
There is enough disk space available: about 40 GB used, 30 GB free.
It never does what it is supposed to efficiently so don’t worry about it. I have never witnessed a defrag reach 0 on any PC.
It will usually say “your drive does not need defragged at this time” but when you look at the analysed graph it is very clear it does need it.
Somebody once told me it is to do with your page file size and if you have a second drive to help it with space for file sorting.
Most of the red band is programs that are in use, the OP or other apps running at that time, so they will never be moved and will always appear red.
I have come across problems when doing multiple defrags so I don’t do multiples anymore.
In general the PC runs well so I only defrag every 3 – 4 moths. But that is just my experience and all PC’s have their individual quirks so see what others post here.
NTFS is very efficient. I don't defrag anymore, my pc runs fast even when fragged at 60%, then all I have to do is delete the restore points and frag drops down to about 15%.
Reporting from experience, defragging can increase the chance of corruption. The process also strains the hard drive actuator arm assembly, which may lead to early disc failure.

Poll ten users and expect ten different opinions. For some, defrag is akin to a religious rite they must practice weekly, while for some like me it is rarely ever.
Provided with only hearsay and lacking any statistics on what may be considered usual or excessive, I can offer only an opinion: because I've yet to notice ANY performance improvement following defrag, my opinion is 'not more than necessary'. I may defrag after deleting bloatware and very large files, but not on a schedule. Because partially filled disks fragment less I maintain plenty of blank space.
Members: I would be very thankful if anyone would provide us with a link to any statistical analysis supporting consistent performance improvement following defrag.
